Hva betyr feilkoden?
The boost pressure sensor receives too high a supply voltage. The fault is intermittent, meaning it comes and goes, and may not be present right now. While the code is active, the engine control module limits boost pressure to the basic level, so the engine feels sluggish and exhaust gas recirculation does not work as it should.
Mulige årsaker
- The supply wire is shorted to battery voltage
- Contact resistance in the connections
- Faulty boost pressure sensor
Hva du kan gjøre
- 1Check the wires and connectors to the boost pressure sensor for chafing, pinch damage and corrosion
- 2Measure with a multimeter that the supply wire to the sensor is not shorted to battery voltage with the ignition on
- 3Because the fault is intermittent, note when the engine feels sluggish, and whether this happens under certain loads
- 4If the engine feels sluggish, avoid heavy loads until the fault has been repaired
- 5Clear the fault code and road test the car. If it returns, have a workshop with diagnostic equipment check the boost pressure sensor and the engine control module
Symptomer du kan merke2
- Poor acceleration and a sluggish engine
- Exhaust gas recirculation (EGR) does not work
Hva feilen kan påvirke2
- Exhaust gas recirculation (EGR) is switched off
- Boost pressure is limited to the basic level
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
